Pádraic Brady is back today with the latest installment (part 5!) of his look at complex views in the Zend Framework. This time, her focuses on something called the Two-Step Pattern - a pattern similar to the Layouts pattern.

Part 5 of our series takes a small time-out from approaching a Composite View solution to reusable Views to take a peek at a simpler approach useful for simpler types of web applications. As we've discussed previously Composite Views allow the nesting of reusable View elements, effectively building a View based on a hierarchy of Views. But often there are simpler solutions to simpler problems. One such solution is the Two-Step View pattern, sometimes called Layouts if implemented in a specific way (as we do below!).

He gives the example of a simple website that needs a header and footer on every page. Rather than having to duplicate the header/footer calls across all of the pages, the Layout (Step-Two) pattern defines a single template that contains the header and footer but also uses a "main" area where the content is dynamically inserted.

He includes a full code example to help illustrate the point - a class, Zps_View, that is fed the path to the layouts and the layout files to use before rendering.
